Flow cytometry plot. The vWF binding capacity of platelets at the days 4 and 7 of storage. (A) The platelets were gated, (B) the binding levels in the negative control in the absence of antibodies to vWF, (C) the vWF binding levels of platelets in the presence of caspase-3 inhibitor at the day 4 of storage, (D) the vWF binding levels of platelets without caspase-3 inhibitor at the day 4 of storage, and (E) the vWF binding levels of platelets in the presence of caspase-3 inhibitor at the day 7 of storage, (F) the vWF binding levels of platelets without caspase-3 inhibitor at the day 7 of storage.
